Seals

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage.

The effectiveness of a seal is dependent on adhesions in the case of sealants and compression in the case of gaskets.

A stationary seal may also be referred to as “packing”

Seal Types:

• Inflatable seal

• Induction sealing or cap sealing

• Adhesive sealants

• Labyrinth seal

• Plug

• Glass-to-metal seal

• Heat seal

Industrial seals are used in various applications in numerous industries. Designed to seal the opening between a static and rotating component, the industrial seal has four important functions:

• Provide pressurized sealing

• Prevent lubrication leaks

• Restrict contaminants from entering the system

• Separation of two components

Manufacturing of mechanical seals involves high precision light engineering activity, as close tolerances have to be maintained on most dimensional and lapped surface finishes to a flatness measured in millionths of an inch . This is critical for effective sealing.

Example Of A Seal Design:

An end face mechanical seal also referred to as a mechanical face seal but simply as a mechanical seal is a type of seal utilized in rotating equipment such as pumps, mixers, blowers and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing leakage can be difficult.

An end face mechanical seal uses both rigid and flexible elements that maintain contact at a sealing interface and slide on each other allowing rotating element to pass through a sealed case. The elements are both hydraulically and mechanically loaded with a spring or other device to maintain contact.

Environmental:

There are no by-products from the manufacturing process of seals. Since the manufacture of mechanical seals is a light precision . Engineering industry, no hazardous chemicals are involved in the manufacturing process.

Ferrous and non-ferrous metal waste is generated during the manufacturing process. Carbon dust is created when carbon materials are turned on a lathe. Liquid waste consists of water soluble coolant oil for machine tools.
